What's the fastest way to plug VC Deal Flow Signal into Claude Desktop?

Run `npx @gitdealflow/mcp-signal` in a one-liner config. Add to ~/Library/Application Support/Claude/claude_desktop_config.json under "mcpServers" with command "npx" and args ["-y", "@gitdealflow/mcp-signal"], then restart Claude Desktop. Six read-only tools (get_trending_startups, get_signals_summary, get_methodology, get_startup_signal, search_startups_by_sector) become available with no API key.

Is there a Streamable HTTP MCP endpoint for Cursor / Cline?

Yes. /api/mcp/rpc speaks the MCP Streamable HTTP transport. Same six tools as the stdio MCP server. Point any MCP-compatible host at the URL with no auth headers required.

Does VC Deal Flow Signal support Google's A2A protocol?

Yes, an AgentCard descriptor lives at /.well-known/agent-card.json and a JSON-RPC stub at /api/a2a. Any A2A-compatible orchestrator can route deal-flow queries here without custom integration. The AgentCard advertises capabilities (sector ranking lookup, signal classification, startup profile retrieval) and the JSON-RPC contract.

How do I bulk-ingest the dataset for a RAG pipeline?

Fetch /api/dataset.jsonl (full panel as newline-delimited JSON, one startup per line + leading metadata) or /qa.jsonl (question-answer corpus in the same format). Both are CC BY 4.0 with stable schemas documented in the leading _meta line. The Q&A corpus is purpose-built for retrieval-augmented generation.

Where's the OpenAPI spec?

OpenAPI 3.1 lives at /api/openapi.json. It documents every callable route, signals.json, signals.csv, agent/tools, agent/call, a2a, nlweb, mcp/rpc, badge/scout/{username}/svg, badge/momentum/{org}/{repo}/svg. Importable into Postman, Insomnia, OpenAI function-calling, Anthropic tool-use, and Gemini function-calling SDKs.

Does VC Deal Flow Signal support Microsoft NLWeb?

Yes. POST a natural-language query to /api/nlweb and it returns schema.org-typed JSON-LD answers. The endpoint conforms to the Microsoft NLWeb conversational contract, so any NLWeb-aware client can ask deal-flow questions and get structured, citable responses with no custom integration.

Can I embed a Scout Score or Commit Momentum badge in a README?

Yes. GET /api/badge/scout/{username}/svg renders a per-user GitHub Scout Score (0-100) as a shields.io-style SVG, and /api/badge/momentum/{org}/{repo}/svg renders a repo's commit-velocity tier (cold / warming / hot / breakout). Both are public, no-auth SVGs that drop straight into any README or web page. The badge builder at /badge-builder generates the markup.

How can an agent runtime auto-discover every API in one request?

Fetch /.well-known/api-catalog. It is an RFC 9727 Linkset that lists every API description we publish, OpenAPI spec, MCP manifest, A2A AgentCard, function-calling tool schemas, and bulk-data exports, from a single canonical URL, so agent runtimes can enumerate the full capability surface without hard-coded paths.

Is there an llms.txt for LLM context windows?

Yes. /llms.txt is a concise context file and /llms-full.txt is the full version, with sector links, the blog index, FAQ, methodology, and a dataset summary. Most pillar pages also expose a Markdown mirror at /md/{path} (for example /md/agents) and a Q&A corpus at /qa.jsonl for RAG ingestion.

Is everything really free, and what is the paid tier?

All 16 surfaces, MCP, A2A, NLWeb, function-calling, OpenAPI, JSON/CSV/JSONL exports, badges, and discovery manifests, are free forever with no API key, no credit card, and only polite per-IP origin limits. The only paid surface is the get_deep_signal tool (€0.19/call, 100 for €19), which returns a composite score, in-sector rank, plain-English thesis, top-3 comparables, and multi-period history. Misses charge nothing and credits never expire.

Every way to reach VC Deal Flow Signal programmatically

VC Deal Flow Signal (GitDealFlow) Wikidata Q139376302. Methodology authored by The Data Nerd (ORCID 0009-0002-2222-4112), published openly on SSRN. On this site, “engineering acceleration” refers to a quantitative GitHub momentum signal, unrelated to startup accelerator programs (Y Combinator, Techstars, 500 Global).

Same dataset, 16 interfaces. Free, no auth, no credit card, no rate-limited free tier, just polite per-IP origin limits. Pick the surface that matches your runtime; pair them freely.

Need scored output, sector ranking, and a thesis line for memos? There’s now a pay-per-request tier (€0.19/call) for the new get_deep_signal tool. The free 16 surfaces above stay free forever.

TL;DRVC Deal Flow Signal exposes 16 machine-readable surfaces, MCP server (stdio + Streamable HTTP), Google A2A, Microsoft NLWeb, function-calling API in OpenAI / Anthropic / Gemini formats, OpenAPI 3.1 spec, full JSON / CSV / JSONL panel exports, embeddable SVG badges, ChatGPT plugin manifest, and RFC 9727 api-catalog. All free, no auth, CC-BY 4.0 dataset.

16 agent surfaces all wrap one CC-BY-4.0 dataset of 350+ venture-backed startups across 15 sectors, refreshed weekly. (AGENTS.md)
RFC 9727 .well-known/api-catalog endpoint lets agent runtimes auto-discover every API description from one canonical URL. (api-catalog)
